Will Ferrell Ejects Shaq From Lakers Game -- Works As Security Guard Named 'Ted Vagina'

Will Ferrell is a Vagina ... Ted Vagina, to be exact ... at least according to the name tag he wore at the Lakers game last night.

Ferrell -- sporting a nicely manicured moustache -- threw on a Staples Center usher uniform (complete with the Vagina name tag) ... and went to work on the court ... keeping the floor safe from basketball hooligans.

At one point, Ted put Shaquille O'Neal in an arm bar -- and escorted the big guy off the court.

Vagina always gets his man.
